Abstract

During the last decade, aluminum alloys discontinuously reinforced with ceramic particulates have received increasing attention for various high-performance applications in automotive, aerospace, and transportation industries due to their high strength-to-weight ratio and superior wear resistance. Particulate-reinforced MMCs can be produced by ingot metallurgy (IM) and powder metallurgy (PM) processing routes. The advantages of PM over IM processing in the fabrication of MMCs include near-net-shape fabrication, lower processing temperatures, and improved microstructural homogeneity. In this study, the authors attempt to fabricate hybrid composites composed of Al-4 wt pct Cu matrix, boron nitride (BN), and SiC particulates. The BN particulates are selected because of their low density (2.3 g/cm{sup 3}) and self-lubricant property. It is expected that BN additions can further substantially improve the wear performance of SiC/Al-4 pct Cu composites.

High strain rate superplasticity of a powder metallurgy SiC particulate reinforced 6061 Al composite (6061/SiC/17. 5p)

Journal Article Nieh, T; Wadsworth, J; Imai, T; ... - Scripta Metallurgica et Materialia; (United States)

One of the major drawbacks of conventional superplastic forming is that the phenomenon is only found at relatively low strain rates, typically about 10[sup [minus]4] to 10[sup [minus]3] s[sup [minus]1]. Recent studies have demonstrated that superlasticity can exist at considerably higher strain rates than 10[sup [minus]3] s[sup [minus]1]. This high-strain-rate superplasticity (HSRS) phenomenon has now been observed principally in metal matrix composites and mechanically alloyed materials, but it has also been observed in more conventionally produced metallic alloys. Metal matrix composites can be fabricated by various techniques, e.g., squeeze casting, vortex methods, compocasting, powder metallurgical (PM) methods, and spray deposition.more »« less

Corrosive wear of SiC whisker- and particulate-reinforced 6061 aluminum alloy composites

Journal Article Yu, S; Ishii, H; Chuang, T - Metallurgical and Materials Transactions. A, Physical Metallurgy and Materials Science

Wear tests on SiC whisker- and SiC particulate-reinforced 6061-T6 aluminum matrix composites (SiCw/Al and SiCp/Al), fabricated using a high pressure infiltration method, were performed in laboratory air, ion-exchanged water and a 3 pct NaCl aqueous solution using a block-on-ring type apparatus. The effects of environment, applied load, and rotational (sliding) speed on the wear properties against a sintered alumina block were evaluated. Electrochemical measurements in ion-exchanged water and a 3 pct NaCl aqueous solution were also made under the same conditions as the wear tests. A comparison was made with the properties of the matrix aluminum alloy 6061-T6. The SiC-reinforcedmore »« less

Influence of extrusion temperature on the aging behavior of 6061Al-15vol%SiC{sub w} composites

Journal Article Borrego, A; Ibanez, J; Lopez, V; ... - Scripta Materialia

It is known that some discontinuously reinforced metal matrix composites, MMCs, with precipitation hardenable matrices, like 6061Al with SiC whiskers or particles, show faster aging behavior than the unreinforced alloys. Regarding the influence of processing techniques on the aging behavior, some investigations have found acceleration on aging of materials consolidated by powder metallurgy (PM) with respect to materials consolidated by ingot metallurgy (IM). This was attributed to the higher presence of oxide inclusions in the PM than in the IM materials. For a given composite preparation technique, however, the influence of the processing variables on the aging response has beenmore »« less

Dry sliding wear of a Ti{sub 50}Ni{sub 25}Cu{sub 25} particulate-reinforced aluminum matrix composite

Journal Article Wang, G; Shi, P; Qi, M; ... - Metallurgical and Materials Transactions. A, Physical Metallurgy and Materials Science

The objective of this article is to characterize the sliding wear behavior of a 30 vol pct Ti{sub 50}Ni{sub 25}Cu{sub 25} particulate-reinforced aluminum matrix composite under dry conditions. The transformation temperatures of Ti{sub 50}Ni{sub 25}Cu{sub 25} particles were measured before and after the compounding procedure by the differential scanning calorimeter (DSC) method. The wear tests were carried out on a pin-on-disc machine. A 10 vol pct SiC particulate-reinforced composite and pure aluminum were chosen as the comparison specimens. The results indicate that Al-30 vol pct Ti{sub 50}Ni{sub 25}Cu{sub 25} composites exhibit higher wear resistance than their unreinforced matrices and aremore »« less

Inertia-friction welding of particulate-reinforced aluminum matrix composites

Conference Cola, M; Baeslack, III, W; Kou, M

Aluminum metal-matrix composites (Al-MMC) are rapidly becoming materials of choice for many aerospace, automotive, recreational sports, and microelectronic applications. The attractive features of these materials include high specific strength and stiffness, a low coefficient of thermal expansion and enhanced wear characteristics relative to monolithic aluminum alloys. The effective engineering application of Al-MMC will commonly require their joining beth to themselves, to dissimilar Al-MMC, and to monolithic aluminum alloys. In the present work, dissimilar-alloy inertia-friction welds were produced between a 6061-T6 Al-MMC tube reinforced with l0 v/o Al{sub x}O{sub 3} particles (W6A.l0A-T6) and a modified A356 case MMC bar reinforced withmore »« less
